    Description

    Schisandrin A inhibits CYP3A activity with an IC50 of 6.60 μM and Ki of 5.83 μM, respectively.

    IC50 & Target[1]

    CYP3A

    6.6 μM (IC50)

    Autophagy

     

    In Vitro

    Schisandrin A (Sch A) strongly inhibits microsomal midazolam 1-hydroxylation catalyzed by CYP3A, with an IC50 of 6.60 μM. The recovery of enzyme activity in the absence or presence of Schisandrin A is shown in dilution assay plots. The Ki value for Schisandrin A is obtained from the Dixon plots and is 5.83 μM. The inactivation of rat liver microsomal midazolam 1-hydroxylation activity by Schisandrin A in the presence of NADPH is found to be time- and concentration-dependent. The Kinact and Ki are estimated to be 0.134/min and 4.51 μM, respectively for Schisandrin A[1].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    In Vivo

    Schisandrin A (SchA) significantly inhibits CYP3A activity in rat hepatic microsomes and Vmax value of each group in a concentration-dependent manner. The double-reciprocal plots and the secondary plot show that Schisandrin A inhibits CYP3A activity, with an apparent Ki value of 30.67 mg/kg. In each Schisandrin A-treated group, Schisandrin A also significantly decreases 1-hydroxymidazolam plasma concentrations compared with the negative group (to levels similar to the positive group)[2].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (6.00 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: 2.5 mg/mL (6.00 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Kinase Assay
    [1]

    For the inactivation of CYP3A4 activity, microsomes are preincubated with inhibitors (Schisandrin A, 2.4 μM, 7.2 μM and 12.0 μM; or Sch B) at 37°C for up to 15 min in the presence of NADPH. Reactions are initiated with the addition of substrate midazolam and incubated at 37°C for 10 min. The enzyme inactivation is analyzed. Duplicates are prepared and tested[1].

    Animal Administration
    [2]

    Rats[2]
    Healthy male Sprague-Dawley rats, weighing 250-280 g and 2-3 months of age, are used. The rats are randomly divided into five groups with 16 rats in each group. The animals are administered once daily for three consecutive days. The Schisandrin A-treated groups are administered intragastrically with doses of 32, 16 or 8 mg/kg of Schisandrin A (physiological saline as vehicle), and the rats are similarly administered with equal volume of vehicle in the negative control group and Ketoconazole (75 mg/kg) in the positive control group. All animals are allowed free access to food but are fasted overnight before scarification to reduce the intestinal content, and each group is randomly divided into two parts with eight rats in each part[2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
